I think giving her notice this week and then letting her know you're going to start a search and would like her to train the new hire.
If she finds a new position right away then two weeks is enough.
Also I recommend writing a letter of reference that she can share with potential employers so you're not taking too many calls, and offering to be available for a call once she's had an interview and trial.
Good luck
Have to politely disagree on part of your post. Yes OP has been generous in keeping her around well after she was needed but that was OP's decision and the Nanny enjoyed it. Nanny should not be penalized now. But I agree that OP should give her notice asap so she can start looking in case it takes a while.
